Electro-sword
From MediaWiki

Like the rest of his sword-wielding Predacon teammates, Tantrum also carries a sword. In his case, it's an electro-sword, which is perpetually sheathed in a web of powerful electric bolts that can disable his prey in addition to being sharp and pointy. Owie.
Insecticon overkill extraordinaire Barrage also packs an electro sword of his own. He mostly just uses it to hack your body into itty-bitty pieces after he’s shot you in the face five times.
